Abstract

Process and device (100) for heat-treating at least one carbon steel wire (1) so as to obtain a homogeneous austenite structure, characterised in that the wire (1) is heated in a tube (2) containing a gas (4) virtually free from forced ventilation, the gas (4) being directly in contact with the wire (1), the time for heating the wire (1) being less than 4 seconds per millimetre of diameter of the wire (1). Pearlitising installation (300) using such a process and such a device. <??>Steel wires obtained according to this process, this device or this installation. <IMAGE>
